6004 ZZ ZVL Deep Groove Ball Bearing 20x42x12

Design and technical characteristics

The 6004 ZZ deep groove ball bearing manufactured by ZVL is a single row ball bearing designed for stable and long-term operation in industrial environments. With standardized dimensions 20x42x12, this bearing is a common and reliable choice for electric motors, pumps, fans and general machinery.

The ZZ metal shields on both sides protect the rolling elements from dust and solid contaminants while allowing high rotational speeds. The deep groove raceway design ensures low friction, smooth rotation and consistent performance throughout the bearing’s service life.

Industrial applications

The 6004 ZZ ZVL deep groove ball bearing is widely used in industrial applications where reliability, repeatable performance and availability are critical. Typical applications include electric motors, gear units, conveyors, production machinery and auxiliary equipment.

Thanks to its design, the bearing can accommodate radial loads as well as moderate axial loads in both directions. It can be installed as a standalone bearing or as part of a complete bearing unit working together with a bearing housing, providing flexibility for machine design and maintenance.

Key advantages for B2B customers

For B2B customers, the 6004 ZZ ZVL offers stable quality, predictable operating parameters and reduced maintenance requirements. Factory lubrication combined with metal shields minimizes downtime and lowers operating costs. This makes the bearing a practical choice for OEMs, maintenance departments and industrial service providers seeking proven standard solutions.

Main product description
